Could quantum decoherence and measurement be deterministic phenomena?
Jean-Marc Sparenberg, Réda Nour, Aylin Manço
The apparent random outcome of a quantum measurement is conjectured to be fundamentally determined by the microscopic state of the macroscopic measurement apparatus. The apparatus…
Device-independent quantum key distribution secure against adversaries with no long-term quantum memory
Stefano Pironio, Lluis Masanes, Anthony Leverrier +1
Device-Independent Quantum Key Distribution (DIQKD) is a formalism that supersedes traditional quantum key distribution, as its security does not rely on any detailed modelling of…
Device-Independent Randomness Generation in the Presence of Weak Cross-Talk
Jonathan Silman, Stefano Pironio, Serge Massar
Device-independent protocols use nonlocality to certify that they are performing properly. This is achieved via Bell experiments on entangled quantum systems, which are kept isolat…
Exploring pure quantum states with maximally mixed reductions
Ludovic Arnaud, Nicolas J. Cerf
We investigate multipartite entanglement for composite quantum systems in a pure state. Using the generalized Bloch representation for n-qubit states, we express the condition that…
No-go theorems for ψ-epistemic models based on a continuity assumption
M. K. Patra, S. Pironio, S. Massar
The quantum state ψis a mathematical object used to determine the probabilities of different outcomes when measuring a physical system. Its fundamental nature has been the subject…
Effects of preparation and measurement misalignments on the security of the BB84 quantum key distribution protocol
Erik Woodhead, Stefano Pironio
The ideal Bennett-Brassard 1984 (BB84) quantum key distribution protocol is based on the preparation and measurement of qubits in two alternative bases differing by an angle of pi/…
Explicit relation between all lower bound techniques for quantum query complexity
Loïck Magnin, Jérémie Roland
The polynomial method and the adversary method are the two main techniques to prove lower bounds on quantum query complexity, and they have so far been considered as unrelated appr…
Security of continuous-variable quantum key distribution against general attacks
Anthony Leverrier, Raúl García-Patrón, Renato Renner +1
We prove the security of Gaussian continuous-variable quantum key distribution against arbitrary attacks in the finite-size regime. The novelty of our proof is to consider symmetri…
Secure and Robust Transmission and Verification of Unknown Quantum States in Minkowski Space
Adrian Kent, Serge Massar, Jonathan Silman
An important class of cryptographic applications of relativistic quantum information work as follows. B generates a random qudit and supplies it to A at point P. A is supposed to t…
Mutual information and Bose-Einstein condensation
C. N. Gagatsos, A. I. Karanikas, G. I. Kordas
In the present work we are studying a bosonic quantum field system at finite temperature, and at zero and non-zero chemical potential. For a simple spatial partition we derive the…
Noiseless loss suppression in quantum optical communication
Michal Micuda, Ivo Straka, Martina Mikova +4
We propose a protocol for conditional suppression of losses in direct quantum state transmission over a lossy quantum channel. The method works by noiselessly attenuating the input…
On the Quantum Theory of Molecules
Brian T. Sutcliffe, R. Guy Woolley
Transition state theory was introduced in the 1930s to account for chemical reactions. Central to this theory is the idea of a potential energy surface (PES). It was assumed that s…
Virtual noiseless amplification and Gaussian post-selection in continuous-variable quantum key distribution
Jaromir Fiurasek, Nicolas J. Cerf
The noiseless amplification or attenuation are two heralded filtering operations that enable respectively to increase or decrease the mean field of any quantum state of light with…
A probabilistic phase-insensitive optical squeezer in peaceful coexistence with causality
C. N. Gagatsos, E. Karpov, N. J. Cerf
A non trace-preserving map describing a probabilistic but heralded noiseless linear amplifier has recently been proposed and experimentally demonstrated. Here, we exhibit another r…
Strong Complementarity and Non-locality in Categorical Quantum Mechanics
Bob Coecke, Ross Duncan, Aleks Kissinger +1
Categorical quantum mechanics studies quantum theory in the framework of dagger-compact closed categories. Using this framework, we establish a tight relationship between two key q…
Classical and quantum partition bound and detector inefficiency
S. Laplante, V. Lerays, J. Roland
We study randomized and quantum efficiency lower bounds in communication complexity. These arise from the study of zero-communication protocols in which players are allowed to abor…
A paradox in bosonic energy computations via semidefinite programming relaxations
M. Navascues, A. Garcia-Saez, A. Acin +2
We show that the recent hierarchy of semidefinite programming relaxations based on non-commutative polynomial optimization and reduced density matrix variational methods exhibits a…
Generalizing entanglement via informational invariance for arbitrary statistical theories
F. Holik, C. Massri, A. Plastino
Given an arbitrary statistical theory, different from quantum mechanics, how to decide which are the nonclassical correlations? We present a formal framework which allows for a def…
Gaussian matrix-product states for coding in bosonic communication channels
Joachim Schäfer, Evgueni Karpov, Nicolas J. Cerf
The communication capacity of Gaussian bosonic channels with memory has recently attracted much interest. Here, we investigate a method to prepare the multimode entangled input sym…
Enhancing quantum entanglement by photon addition and subtraction
Carlos Navarrete-Benlloch, Raúl García-Patrón, Jeffrey H. Shapiro +1
The non-Gaussian operations effected by adding or subtracting a photon on the entangled optical beams emerging from a parametric down-conversion process have been suggested to enha…
Quantum uncertainty relation saturated by the eigenstates of the harmonic oscillator
A. Mandilara, N. J. Cerf
We re-derive the Schrödinger-Robertson uncertainty principle for the position and momentum of a quantum particle. Our derivation does not directly employ commutation relations, but…
